The invention discloses a method for enabling an automobile storage battery to be compatible with a lead-acid battery and a lithium battery, and the method comprises the steps: detecting the cell voltage, cell temperature, current, voltage difference and current residual current SOC information of a 12V lithium battery through a battery management system, and transmitting the detection information to a whole vehicle CAN network; detecting the power supply voltage KL30 voltage of the lead-acid battery by a vehicle control unit VCU, and confirming the real SOC of the current storage battery; detecting the state information of the lead-acid battery and the lithium battery by the whole vehicle system, and displaying the state information to a user; a user switches the storage battery according to the displayed information, the state of the storage battery is confirmed after the vehicle is powered on from low-voltage power-off of the whole vehicle, the type of the storage battery assembled on the whole vehicle is confirmed in combination with CAN signals, KL30 voltage, charging and discharging voltage reduction, large-screen engineering mode selection and the like, different charging and discharging management modes are entered according to the type, and the method is safe, reliable and high in practicability. The types of the storage batteries of the whole vehicle are judged in a multi-dimensional mode, so that different charging and discharging modes are selected.

    本发明公开了一种汽车蓄电池兼容铅酸电池和锂电池的方法,本发明通过电池管理系统对12V锂电池的电芯电压、电芯温度、电流、压差、当前剩余电流SOC的信息进行检测,并检测信息发送到整车CAN网络中;由整车控制器VCU检测铅酸电池的电源电压KL30电压,确认当前蓄电池的真实SOC;由整车系统检测铅酸电池和锂电池的状态信息,并将状态信息展示给用户;用户根据展示的信息进行切换蓄电池,并由车辆从整车低压下电到上电后确认蓄电池状态,结合CAN信号、KL30电压、充放电降压、大屏工程模式选择等确认整车上装配的蓄电池类型,根据类型进入不同的充放电管理模式,安全可靠,通过多维度判断整车蓄电池类型,以选取不同的充放电模式。
